Connecting multiple inverters to a data logger
► If the data logger does not have an integrated RS485 termi-
nation resistor, switch on the RS485 termination resistor on
the first inverter.
► After commissioning the inverters, set a unique inverter ID
for each, see “Inverter ID”, page 23

ATTENTION
Unwanted currents .
Unwanted currents can flow when multiple
inverters are connected via RS485
► Do not use GND and VCC
► If the cable shield is used for providing
lightning protection then the housing of only
one inverter in the RS485 chain should be
grounded
